The Tesla Coil is a transformer designed by Nikola Tesla in 1891 to produce high voltage, low current electricity. In high voltage news, Tesla has been subpoenaed by the US regulator, the Securities and Exchange Commission (SEC) over one of Elon Musk’s recent tweets. The tweet outlined his potential plan to take Tesla private, so the SEC are now investigating for market manipulation as the tweet caused dramatic increases to Tesla’s share price. Musk has confirmed that he has funding from the sovereign wealth fund of Saudi Arabia, but the share price has dropped again after the news of the SEC’s subpoena, which could lead to complications should he move forward with taking Tesla private.

The Turkish lira has been starting to recover since its recent low last week but has still lost over 35% against the dollar year to date.

Within commodities, metals have dropped almost 20% since their peak in April of this year, leading them also nearly into bear territory.

UK inflation increased in July, up to 2.5%, as a result of rising prices for computer games and transport fares.

This is the first month since last November that inflation has increased. UK unemployment figures were also released last week, hitting the lowest figure of unemployment seen since 1975, at 4%.
